ALARM 0R SIGNAL APPARATUS.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application filed May 19, 1914. Serial No. 839,510.

To all whom it may concern."

Be it known that I, IRA E. STUMP, a citizen of the United States,residing at Cleveland, in the county of Guyahoga and State of Ohio, haveinvented certain new and useful Improvements in Alarm or SignalingApparatus, of which the following is a specification.

My invention relates to improvements in alarm or signaling apparatus,and is particularly designed and adapted for use in connection withself-propelled vehicle, such as automobiles, motor trucks, and the like,where an air cooling fan is employed at the rear of the radiator and infront of the engine or motor cylinders for directing currents of airover the latter for cooling the same.

The improved alarm or signaling apparatus is particularly designed foruse in connection with or as a part of such air cooling fan in givingtherequisite alarm or signal.

The primary object of the invention is to provide a generally improvedalarm or signaling apparatus of exceedingly simple, cheap, and eflicientconstruction, the improved apparatus including a centrally locateddiaphragm suitably mounted within the hub portion of the fan and adaptedto be carried by the latter while being rotated.

With the above mentioned, and other ends in view, the invention consistsin the novel construction arrangement, and combination of parts,hereinafter described, illustrated in one of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this specification, Figure1, is a front elevation of an air cooling fan embodying my improvedsignaling apparatus, a portion of the walls of the fan blades and hubbeing broken away for the purpose of clearer illustration of the parts.

Fig. 2 is a central sectional View taken on line 22 of Fig. 1.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved alarm or signaling appara tus comprises a fan consisting,in the present instance, of a hollow drum or hub portion 1, anda'plurality of radially extending tubular fan blades or arms 2, saidtubular fan blades being flattened and suitably inclined as shown mostclearly in Fig. 2 of the drawings.

The improved fan is adapted to be mounted at the rear of the automobileradiator and in front of the engine cylinders in the usual manner bymeans of an attaching bracket 3, provided with suitable bearing members4, the latter supporting a stub or hub driving shaft 5, said drivingshaft being adapted to receive its motion through the medium of asuitable pulley 6, which may receive its motion through a suitablebelting or sprocket chain (not shown) communicating with a suitablesource of power.

As a suitable source of sound, a sound dia phragm 7, is provided, saiddiaphragm 7,

in the present instance, being of circular ordisk shape and preferablybeing provided on the one side with a circular series of corrugations orprojections 7 which latter may be pressed out or formed integral withthe diaphragm 7.

As a suitable means of mounting the diaphragm truss rods 8, are providedsaid rods being preferably provided with hooked heads 8*, passingthrough suitable openings near the outer periphery of the disk shapeddiaphragm and being threaded at their outer ends for connection to andadjustment by threaded sleeve screws 9, which latter may be mounted inand supported by suitable cross bars or members 10, extending across theopen ends of the flattened tubular shaped fan blades 2.

It will be observed that the tubular fan blades are adapted to act assound conducting elements for the transmission of the sound waves fromthe diaphragm when the latter is thrown into motion or vibration by themechanism hereinafter described.

As a means of vibrating the diaphragm 7 as revolved and carried by therotating fan a pin or shaft 11, is mounted in the hub driving shaft 5,said pin being adapted to be moved longitudinally within the shaft 5,and against the resistance of a spring 12 through the medium of asuitable cord or actuating device (not shown) connected to the loop head11, and as a means for preventing the circumferential movement of thepin or bar 11, the latter is provided with a groove 11*, adapted toreceive and contain the end of a bracket 3 extending upwardly from thestationary attaching bracket 3.

r The outer end of the slidably mounted pin or shaft 11, is providedwith an arm 13, extending upwardly and carrying a roller head 14, whichlatter is adapted to be drawn toward and to strike against thecorrugations or projections 7 of the diaphragm to vibrate the latterwhen the pin or shaft 11, is drawn rearwardly against the resistance ofthe spring 12, in an obvious manner by the attached operating mechanism.hereinbefore referred to. 7
